Summary: This study tested the hypothesis of no difference in bone regeneration after maxillary sinus floor augmentation using different ratios of iliac or mandibular autograft and deproteinized bovine bone mineral. The results showed that the percentage of bone regeneration significantly increased with a higher ratio of autograft, regardless of the origin of the graft.

Summary: This study compared bone density changes and initial implant stability following sinus augmentation using autogenous bone (AB) versus fresh frozen bone (FFB). The results showed no significant differences in bone density between the two groups at different time points, but the FFB group had significantly higher implant insertion torque and a greater number of patients achieving insertion torque >32 N/cm. The use of FFB for sinus augmentation was found to be a reliable option, providing predictable initial implant stability and osseointegration while avoiding unnecessary morbidity associated with AB harvesting.

Summary: The study aimed to compare the microarchitecture of augmented bone following maxillary sinus augmentation using A-PRF and SACBA after 3 and 6 months of healing. Results showed no significant differences in morphometric parameters between the test and control groups, indicating a potential reduction in treatment time with the use of A-PRF and SACBAs for two-stage MSA.

Summary: The effects of deproteinized bovine bone (DBB) and freeze-dried bone allograft (FDBA) on bone healing during maxillary sinus floor augmentation were investigated. The FDBA group showed higher gene expression of Opn, Runx2, and Rankl compared to the DBB group. FDBA had an expression pattern similar to native bone and may be clinically preferable over DBB.

Summary: Both DBBMC alone and DBBMC-EMD treated sites experienced significant reduction in ridge width 4 months post-extraction, with no significant changes in buccal or palatal bone height. Thinner initial buccal wall thickness (< 1 mm) resulted in greater alveolar ridge reduction. Addition of EMD to DBBMC led to increased new bone formation in the test group and less residual graft compared to the control group.

Summary: This study aimed to evaluate the spatial distribution and compaction of bone graft particles in the maxillary sinus after maxillary sinus floor augmentation and their association with bone regeneration. The study found that excessive compaction of bone graft particles can negatively affect their integration with the native bone, highlighting the importance of avoiding excessive compaction to optimize the macrostructural environment for bone regeneration.

Summary: The study found that DBBM is a reliable graft material for maxillary sinus augmentation even in the early period. Combining DBBM with liquid PRF contributed to new bone formation over a four-month period, but this contribution was not statistically significant.

Summary: The study found that the addition of BM and the type of implant surface did not have a significant impact on osseointegration in areas grafted with sintered deproteinized bovine bone at high temperatures. There were no differences observed in the quantity of mineralized tissues around the implants or the bone-implant contact between the different groups assessed.

Summary: There are various cysts and tumors in the mandibular and maxillary bones, with origins either odontogenic or otherwise. The odontogenic keratocyst (OKC) is a common example of an odontogenic cyst. Although the treatment methods for OKC have not changed significantly, it has a higher recurrence rate compared to other odontogenic cysts. The size, location, and cortical expansion of the OKC can influence the treatment and potential recurrence. Individual cases may require bone grafting or other reconstruction methods. Proper treatment of the bone cavity after cyst removal is crucial for preventing pathological fractures or improper healing. Healing potential can be improved with xenograft bone substitutes or allograft fresh-frozen bones. In rare cases, a titanium plate may be used for mandibular stability. This case report presents an atypical case of a large OKC treated with fresh-frozen bone grafts and supported with collagen barrier material.

Summary: This study investigates the effects of thermal alteration on the microstructure of human bones and teeth through whole-body experiments. The results show some microscopic changes post-burning and suggest that histological age-at-death estimation methods can be applied to bones and teeth post-burning. The presence and amount of soft tissue on remains affect the degree of burning and the amount of bone remaining for analysis.

Summary: This study compared the damaging effects of a synthetic graft and a xenogeneic graft on rabbit sinus mucosa. The results showed that the mucosa in contact with graft particles experienced progressive thinning and perforations. The damaging effects increased over time, and were more pronounced with the xenogeneic graft compared to the synthetic graft.

Summary: This study compared the healing of collagenated and non-collagenated xenografts used for maxillary sinus floor elevation. The results showed that the collagenated xenograft underwent higher resorption and resulted in greater new bone formation. The region adjacent to the bone wall was found to have the highest new bone content, which is clinically relevant as it is where the implant will be installed.

Summary: The aim of this study was to compare the damaging effects of two xenografts with different resorbability rates on the Schneiderian membrane (SM). The results showed that the deproteinized bovine bone mineral (DBBM) group had more damage compared to the swine collagenated corticocancellous bone group. Furthermore, inward displacement of the bone window and placement of a collagen membrane adjacent to the SM offered protection from damage.

Summary: The study aims to describe the histological events following maxillary sinus floor elevation when the elevated and undetached sinus mucosa are in close proximity or in contact with each other. Histological analysis of 152 elevated maxillary sinuses from 76 rabbits was conducted. The results showed that the width of the pseudostratified columnar epithelium and the distance between the two layers of the elevated and undetached sinus mucosae were measured at different standardized positions. Adhesion of the mucosa was observed in 31 sites, with 12 sites in the proximity stage showing shortened cilia and interlinked epithelial layers, as well as hyperactivity of goblet cells. Fusion and synechia stages were also observed.

Summary: This study compared the bone incorporation and remodeling processes of xenogeneic en bloc grafts placed using two bone grafting techniques, onlay and inlay. The results showed that the percentage of new bone increased faster and was higher in the inlay grafts than in the onlay grafts. This might be related to the self-contained conformation of the recipient site in the inlay group.

Summary: The purpose of this study was to utilize the break-even point concept to describe the changes in bone formation and resorption around implants. Data from human and dog studies were analyzed to determine the break-even point of bone density. The results showed that the occurrence of the break-even point varied depending on the location and surface characteristics of the implants. Overall, this study highlights the importance of considering different factors when evaluating bone modeling around implants.

Summary: The worldwide popularity of E-bikes and P-scooters has led to an increase in associated injuries. This study evaluated the role of rider age in injury severity and found that older age did not significantly increase the need for hospitalization. Patients who underwent imaging evaluation had lower hospitalization risk, while those who had surgery or longer operative procedures had higher risk.

Summary: The worldwide increase in E-bike and P-scooter use has led to a rise in associated injuries. This study evaluated trends in incidence and types of injuries in riders evacuated to a tertiary ED. The results showed a steady increase in ED visits and referrals for hospitalization, indicating severe injury. Upper and lower extremities were the most common injury sites, with variations among age groups. Safety regulations, including licensing requirements and mandatory protective gear, are needed to protect riders, especially in high-risk anatomical sites.

Summary: This study evaluated the damaging effects of two different bovine bone grafts on the sinus mucosa after sinus augmentation. The results showed that the contact with bovine xenografts resulted in thinning and perforations of the sinus mucosa, with no differences between the two grafts in the numbers of thinning mucosa sites and perforations.
